APPARATUS FOR DISTRIBUTING COMPRESSED AIR FOR PURPOSES on VENTILATION.

Specification of Letters Patent. Applicationfiled May 17, 1907. SerialNo. 374,263.

' Patented May 18, 1909..-

Be it known thatiwe, HUGO ARNDT, a subject of theEmperor of Germany,residing at 29 Elizabethufer, Berlin, in the Empire of, Germany, factoryowner, and ALBERT N IJ'RN- BERG, a subject of the Emperor of Germany,residing at 8Cl1aussest1'asse, Berlin, in the l Empire of ermany,engineer, have invented certain new and useful Improvements in Apparatusfor Distributing Compressed Air for Purposes of Ventilation, followingis aspecification. This invention relates to apparatus for dis- 1tributmg compressed air for purposes of Wu tilation. It belongszto theknown type of air 1. Apparatus for'dlstrlbut'in distributing apparatusin connection with which the air flows out of a pipc inthe form of astar,'and the pipe is rotated through the the outflowing gaseous body.

trlbuting arms are in the form of hollow vanes, which rotate around thesame axis.

The compressed air flowing out of .these vanes is'projected into theroom through the rapid rotation of the vanes but after passing out'is-:.fu,rther dispersed by the following vane.. v

The-improved apparatus is illustrated. in the accompanying drawing,Figure 1 being a longitudinal section and Fig. 2 an eleva-. tion of theapparatus. Fig. 3 is a transverse fiction-taken through 66 of the vanesor a es.

A'hollow bo'dy'l is rot'zit ively seated on a suitably drilled cone 2,which is attached to the admission pipe for the compressed air. I On tothis hollow body 1 pieces of piping 3 secured, which piping howevercanbe rotated somewhat, so as toenable the hollow vanes 4 which are fixed lthereon tobeadjusted'more or'l'ess obliquely to theiraxis of rotation.The vanes 4 are retained in the position given to them by means of thejam-nuts] The vanes or blades are .com osed of two metal plates, whichare fixer to the pieces of piping 3 and tightly soldered over the wholecircumference with the exception of one place for example, as shown, Ion the edge of the vane where indicated by l of which the the numeral 6,where a slot is left open, in the same place on each vane, and out ofwhich the compressed-air flows. The slot may be replaced by a row ofholes. Two or more of such vanes or blades may be arranged on thehollow-body 1. If now in the'case of all the existing vancsithecompressed airpass'es out at ,6, it exercises a reactive action, throughwhich the vane-wheel thus constructed is caused to rotate. Thedistribution'of the air is thus effected in the manner described above.

Having fully described our invention, what we claim and desire to secureby Letters Patan by reaction comprising aiconical body connected to theair admission pipe, conduits .or ways in said conical body openingcommunication between the admission pipe and the exterior of the cone, ahollow casing rotatively mounted on said cone, and hollow vanes orblades mounted on said casing and in open communication with itsinterior, said vanes having screw-threaded stems fitting screw-tap edopenings in said casin and be ing provi ed with jam nuts and out ingssubstantially as described and-for the purpose stated.

2. A air by reaction comprising a conica body connected to the airadmission'pipe, conduits et open-' pparatus for distributing com -rssed.

or ways injsaid conical body openlng commuexterior of the cone, a

nication with its interior and out et' openings in said vanes or bladessubstantially as de-' scribed and for the purpose stated.

In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses this 2nd day of May 1907.
